ASCO Numatics Refinery Applications

ASCO Pilot Valves for Dust Collector Applications

ASCO Pilot Valves

These 3-way and 4-way models are the refining industry's most varied, proven, and widely used solenoid pilot valves. They're applied throughout the
plant as the primary devices for process valve actuation, as well as the shutdown valve when used with digital valve controllers for on-off and control
valve applications. Their high flows allow more cycles and maximize throughput.

Select from Standard, 0.55 W and 1.4 W Low Power, Intrinsically Safe, and Non-Incendive Field Wiring Solenoid Valves. Exida certified SIL 3 capable constructions are available.

ASCO Refining Manual Reset Valves
ASCO Manual Reset Valves

Nothing else can match the level of trust our best-selling solenoid pilot valves inspire in lever-operated manual reset applications. Their corrosion-resistant
materials and industrial-strength components
have helped make them a legend in harsh refining environments. Apply wherever human interaction is recommended — and absolute reliability is essential.

ASCO Refinery RCS Safety Application Valves
ASCO Safety Application Valves

We're also the acknowledged leaders in solenoid pilot valves used with safety instrumented systems (SIS) and similar applications in critical refinery locations. Example: our ASCO RCS is a redundant control system that acts as a single three-way valve. Features include the ability to perform online testing of the redundant solenoid valves, and automatic partial stoke testing of the process valve. You get ensured functional safety with unequaled reliability.

ASCO Numatics Refinery Application - Actuated Globe Valve Assemblies
ASCO Actuated Globe Valve Assemblies

ASCO 2-way piston operated process valve assembly with HS Series position indicator. A cost effective alternative to an actuated ball valve assembly, this linear on/off valve is your stand alone solution for a variety of process applications.

ASCO Stainless Steel Filter Regulator
ASCO Filters & Regulators

These filters and regulators treat air quality and regulate pressure in your plants pneumatic systems. Apply them throughout the refinery to control pressure or meet filtration requirements. These high-performance products are available in multiple configurations and materials, including full 316L Stainless Steel for use in
corrosive environments.
